' IMPROVEMENT IN ELECTRO-NIAGNETlCrWATER-ELEVATORS.

To all whom 'it mq/jcoizcewu' Be it known thattl, SrLAs G. RANDALL, ofthe city and county ofmljrovidence, and State of Rhode Island, haveinvented a certain new and useful Electro-Magnetic Water-Elevator.

My invention consists in combining an electromagnet, operated by anysuitable battery, with a water-elevating apparatus, in such a mannerthat the mechanism will be operated automatically by the magnetic forceof the battery 5 and I do hereby declare that the following'specification, taken in connection with the drawing furnished andforming a part of the same, is a true, clear, and exact descriptionthereof.

Referring to the drawing, Figure l represents the apparatus inperspective. Fig. 2 represents the same in cross-vertical section.

A represents the outer vessel of a common form of battery 5 B, the innervessel. C is an iron horse-shoe magnet secured to a suitable frame-workor vertical foundation. This magnet is in the usual form ofelectro-magnets, and is connected to the inner vessel B by the wire a.The two arms oi the magnet are connected by means of the wires al andd2. The end of the wire af, adjacent to the vessel B, is pivoted so asto admit of its elevation or separation from contact with the battery.The outer vessel A is connected with the magnet by contact of the wireb, which, when its free end is in contact with the wire al, (which alsohas a free end,) perfects the circuit and charges the magnet. D is aslide, to which the lower or free end of the wire b is attached. Whenthe slide is at.its lowest point, the lower end of Jthe wire b restsupon the free or outer end of the wire a1. This slide is so set that itwill not fall of its own weight, being held in any position it may beplaced in by light frictional bearings. E is an iron armature with rodsc and c passing upward through each end, with insulated connections. Therod cis so bent that it enters a slot, m, in the slide D. Both of therods pass through guide-apertures in the shelf z', which support thearmature. F is a pump. It is composed of a self-expanding chamber ofrubber, an induction-valve,f, and an eduction-valve, g. Beneath thechamber and in close contact l Spcication forming part of Letters PatentNo. 119,996, dated October 17, 1871.

with it is a cross-bar, h, to each end of which is secured the rods cand c', connecting it with the iron armature E.- G is an air-chamber, socalled, communicating with the pump by means of valve g. Suitable pipesare attached to this chamber by -which water is conveyed to any desiredpoint. It is to be observed that a wire or cord is attached to the upperor pivoted end of the wire a. rlhe other end of this wire or cord may beplaced at any desired convenient position. By it the action of theapparatus may be controlled by elevating or lowering the end of the wireaf, by which the electric circuit may be broken or continued.

The operation of the apparatus is as follows: It is to be assumed thatthe battery is properly charged, and the pivoted end of the wire a incontact with the battery, with the en ds of wires al and b also incontact. An electric current charges the magnet G, which attracts thearmature E. As the armature ascends the upper end of the rod c movesfreely up along the slot m in slide D until the' curved portion of therod comes in-contac`t with the upper end of the slot. By the slightcontinued upper movement of the armature and its rod c, the slide D iselevated sufficiently to lift the lower' end 'of the wire b from contactwith the outer end of the wire al, thus breaking the circuit and causingthe magnet to drop the armature. As the armature descends the curved endof the rod c moves freely down the slot m until it comes in contact withits lower end, when it carries down the slide so that the wires'b and alare again brought in contact, when the operation described is repeated,and so on, alternately up and down, continuing as long as the battery issupplied with chemicals, or so long as the upper end of the wire a isleft in contact with the battery. The lower ends of the rods c and cbeing connected to the ends of the cross-bar h, and the latter beingconnected to the under side of the expansive pumpchamber F, it isobvious that every movement of the armature causes a correspondingmovement in the pump, by which water is drawn into and forced from it inacontinuous stream. A

.self-expansive chamber is deemed preferable toidleness 2 a piston andcylinder'7 on account of its operaeiated automatically by the movementof the tion being in a measure frietionless. If desired7 armatureattached to a suitable circuit-breaking the self-expansive chamber maybe assisted in its device7 as and for the purposes specified.
